https://www.maximizemarketresearch.com/market-report/global-hydroxyproline-market/88252/ Hydroxyproline is one of the particular amino acids found in collagens, which are Matrix Metalloproteases substrates. The post-translational hydroxylation of proline yields hydroxyproline i.e. OHP. Proline lowers collagen elasticity whereas OHP promotes it. Dietary intake and bone reabsorption are the two main sources of circulatory OHP. OHP enters the bloodstream as a result of bone disintegration and collagen breakdown. Gene mutations that cause a change in the proline and OHP level of collagen cause disorders that alter elasticity. As a result, rather than being a Biodegradable Temporizing Matrix, OHP is a biomarker of collagen breakdown. Prolyl-hydroxyproline, a dipeptide produced from collagen, has been linked to osteoblast development.
